Ukraine’s Wladimir Klitschko (60-3, 52 KOs), 37, who has held his heavyweight title for seven years, defends his crown for the 15th time against 34-year-old Russian Alexander Povetkin (26-0, 18 KOs), a challenger many regard as a formidable test. The Moscow venue of 12-round clash – Klitschko’s 18th appearance on HBO – will draw enthusiastic fans of both men, adding to the excitement of the contest.

The main event pits superstar Miguel Cotto (37-4, 30 KOs), 32, from Caguas, Puerto Rico against intriguing challenger Delvin Rodriguez (28-6-3, 16 KOs), 33, of the Dominican Republic in a 12-round super welterweight battle. Making his 19th appearance on HBO, Cotto looks to reignite his hall of fame-caliber career after two tough setbacks last year. Though he trained in Orlando for his last three fights, Cotto now holds camp at the famed Wild Card in Hollywood under the supervision of legendary trainer Freddie Roach. Rodriguez, who now calls Danbury, Conn. home, seeks to pull off a major upset.
